Abstract

Devices and methods useful for transluminally accessing a body cavity are disclosed. In one embodiment, a transluminal access device adapted to be inserted through a body lumen is provided and can include an inner shaft having an opening at its distal end and adapted to be positioned adjacent to an inner wall of a body lumen. The inner shaft can include one or more sealing mechanisms, such as one or more seals with suction ports formed thereon for isolating a portion of a body lumen. The isolated portion may be sterilized and serve as an access point or otomy site for penetrating the wall of the body lumen to access a body cavity.

Claims

1. A transluminal access device, comprising:

an inner shaft adapted to be inserted through a body lumen and having proximal and distal ends with an inner lumen extending therethrough, the distal end including an opening adapted to be positioned adjacent to an inner wall of a body lumen containing the inner shaft; and

a sealing mechanism at least partially disposed around the inner shaft and adapted to isolate the opening within a portion of a body lumen containing the inner shaft.

2. The device of claim 1, further comprising an outer shaft disposed around a least a portion of the inner shaft, the sealing mechanism being coupled to a distal portion of the outer shaft.

3. The device of claim 2, wherein the sealing mechanism comprises a first annular seal formed on a distal tip coupled to a distal end of the outer shaft and positioned distal of the opening, and a second annular seal formed on the distal end of the outer shaft and positioned proximal of the opening.

4. The device of claim 3, wherein the first and second annular seals are adapted to form a seal around an inner wall of a body lumen.

5. The device of claim 4, wherein the first and second annular seals each include a plurality of suctions ports formed around an outer perimeter thereof and adapted to suction tissue onto the first and second annular seals.

6. The device of claim 1, further comprising an expandable member disposed around the opening and adapted to stabilize the opening relative to a tissue surface.

7. The device of claim 3, wherein the distal tip is coupled to the distal end of the outer shaft by one or more struts extending therebetween.

8. The device of claim 3, further comprising an optical viewing instrument associated with the distal tip of the outer shaft.

9. The device of claim 1, wherein the opening is formed in a sidewall of the inner shaft.

10. A method for processing the device of claim 1 for surgery, comprising:

a) obtaining the device of claim 1;

b) sterilizing the device; and

c) storing the device in a sterile container.

11. A transluminal access system, comprising:

an outer shaft having proximal and distal ends with an inner lumen extending therethrough, the outer shaft being adapted to be inserted through a body lumen;

an access element extending from the distal end of the outer shaft and having at least one opening formed therein and adapted to be positioned adjacent to an inner wall of a body lumen;

a first annular seal coupled to the outer shaft and positioned distal of the opening, the first annular seal being adapted to form a seal with an inner wall of a body lumen; and

a second annular seal coupled to the outer shaft and positioned proximal of the opening, the second annular seal being adapted to form a seal with an inner wall of a body lumen.

12. The system of claim 11, wherein the access element comprises an inner shaft extending through the outer shaft.

13. The system of claim 12, wherein the opening is formed in a sidewall of the inner shaft adjacent to a distal end of the inner shaft.

14. The system of claim 11, wherein the first and second annular seals are adapted to form a seal around an inner wall of a body lumen.

15. The system of claim 14, wherein the first and second annular seals each include a plurality of suctions ports formed around an outer perimeter thereof and adapted to suction tissue onto the first and second annular seals.

16. The system of claim 11, wherein the first annular seal is formed on a distal tip coupled to and spaced apart from the distal end of the outer shaft, and the second annular seal is disposed around the distal end of the outer shaft.

17. The system of claim 16, wherein the distal tip is capped to prevent fluid flow therethrough.

18. The system of claim 11, further comprising an expandable member disposed around the opening and adapted to stabilize the opening relative to a tissue surface.

19. The system of claim 11, further comprising an optical viewing instrument associated with the distal end of the outer shaft.

20. The system of claim 11, wherein at least a portion of the outer shaft and the access element are flexible to allow the outer shaft and access element to be inserted through a tortuous lumen.

21. A method for accessing a body cavity, comprising:

positioning an access port located on a distal end of an inner shaft adjacent to an inner wall of a body lumen;

isolating a section of the body lumen containing the access port from a remainder of the body lumen;

sterilizing the isolated section of the body lumen; and

penetrating through the inner wall of the body lumen to provide access through the access port to a body cavity positioned adjacent to the body lumen.

22. The method of claim 21, wherein isolating a section of the body lumen containing the opening comprises forming a first seal with the inner wall of the body lumen at a location distal to the access port, and forming a second seal with the inner wall of the body lumen at a location proximal to the access port.

23. The method of claim 22, wherein the first and second seals are formed by suctioning the inner wall of the body lumen using an annular sealing mechanism.

24. The method of claim 23, wherein the first seal is formed around an outer surface of a distal tip that is adapted to prevent fluid flow therethrough, and the second seal is formed around an outer shaft disposed around the inner shaft.

25. The method of claim 24, wherein sterilizing the isolated section of the body lumen comprises introducing an irrigation through the outer shaft.

26. The method of claim 21, wherein positioning the access port comprises advancing the inner shaft through a colon.

27. The method of claim 21, wherein the access port is formed in a sidewall of the inner shaft and faces an inner wall of the body lumen.

28. The method of claim 21, further including the step of sterilizing said device after at least one use.
